Description

[Detailed description of the invention] The present invention relates to a sliding door, more specifically, a sliding door that is framed in a rectangular shape by left and right stile, upper and lower horizontal stile, and a middle sill, and a handle is provided at the connection between the stile and the middle stile. be.

Conventionally, as shown in Japanese Utility Model Publication No. 54-14700, insertion pieces of joint pieces that also serve as pulls were press-fitted into both ends of the middle crosspiece, and the locking pieces of the joint pieces were inserted into the locking grooves of the left and right frames. At the same time, a net is stretched across the left and right frames, and the left and right frames and the middle frame are connected by the tension of the stretched net. An assembled sliding door that does not come off has been proposed.

However, with this structure, if the net becomes slack, the fixation between the middle crosspiece and the frame becomes unstable, causing looseness and reducing the rigidity of the sliding door. The problem is that the fixation becomes unstable and rattling occurs, making the opening and closing operations of the sliding door uncomfortable.

In addition, when the above-mentioned technology is used to connect a frame and a middle frame of a sliding door, a glass door, a bathroom sliding door, etc., the joint of the glass mounting groove at the joint between the frame and the middle frame is simply a glass mounting groove. Since the forming side walls are only in contact with each other in a perpendicular state, there is a problem that light easily leaks from this joint.

Further, as shown in Japanese Utility Model Application Publication No. 52-13644, the inward edge of the glass mounting groove forming side wall of the stile is cut out to form a recess, and the handle is fitted into the recess into the notch at the end of the middle crosspiece. A sliding door has been proposed in which the middle frame and the frame are connected by inserting and fixing them.

However, this structure has the disadvantage that the concave portion must be carefully cut out, which is time-consuming and troublesome to process.

In addition, the handle is restricted from moving in the sliding door opening/closing direction by the depth wall surface at the notch at the end of the middle crosspiece and the top surface of the side wall forming the glass mounting groove of the frame, so the notch at the end of the middle crosspiece is If the accuracy deteriorates even a little, the handle installation will become loose.

In addition, as mentioned above, the sliding door is only fixed by fitting into the notch at the end of the middle frame and the notch in the frame, so if the sliding door is opened and closed repeatedly, the handle may become distorted or the handle may become distorted. The fitting condition deteriorates due to the impact caused by the sliding door, causing looseness in the installation of the handle, which causes discomfort when opening and closing the sliding door.

As mentioned above, various methods have been proposed in which the wing roots and the middle crosspiece that make up the sliding door are connected via a handle, but these methods reduce the rigidity of the sliding door or cause the handle to wobble. It has problems such as causing confusion when opening and closing, light leaking easily from the joint between the stile and the middle frame, and the processing is troublesome.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a sliding door that can connect the stile and middle crosspiece of the sliding door via a handle, and that can eliminate all of the above-mentioned problems.
